Detex FV50 Fire-Rated Surface Vertical Rod Exit Device | Alarm and 09BN Storeroom Trim Options | 36 x 84 in.

The Detex FV50 Value Series Fire-Rated Surface Vertical Rod (SVR) Exit Device is heavy-duty exit hardware designed for manufacturer-approved fire-rated commercial door assemblies. This product combines a 36-inch touchbar exit device for 3-foot-wide doors with surface-mounted top and bottom vertical rods sized for an 84-inch (7-foot) door height. Its standard 96 surface top strike and less-dogging (LD) configuration support positive latching on approved fire-exit openings.

Choose the exact factory configuration below. The FV50 LD 628 96 36X84 is the standard, non-alarmed fire-exit device with 628 satin-aluminum finish. The FV50 EB LD 628 96 36X84 adds a 9V battery-operated audible exit alarm in the same 628 finish. The FV50 EB LD 711 96 36X84 provides the same EB alarm in 711 satin-black anodized aluminum. Neither the standard FV50 LD nor the FV5009BN LD has the EB battery alarm, alarm indicators, alarm control or alarm battery. The FV5009BN LD 628 96 36X84 instead includes 09BN Function 09 storeroom S-lever outside trim with a 689 aluminum-painted lever and narrow escutcheon supplied alongside the 628 satin-aluminum device rail. This 09BN keyed lever is released by an authorized key and locks again when the key is removed; a compatible operating mortise cylinder and keys are required and sold separately.

Choose Your Configuration

Important ordering distinction: EB in the model number identifies the battery-operated exit alarm. A model without EB, such as FV50 LD 628 96 36X84, is a mechanical, non-alarmed fire-exit device. All four listed configurations are less-dogging, use surface vertical rods, and are specified for the same nominal door size. FV5009BN identifies the FV50 plus the supplied Function 09 storeroom lever trim, not a special alarm: a model without EB has no battery exit alarm. Standard FV50 LD includes no outside trim; FV5009BN LD includes 09BN trim but does not include the operating mortise cylinder.

Features and Benefits

• Detex FV50 fire-exit hardware: Fire-rated version of the V50 surface vertical rod device for compatible commercial fire doors. Detex fire listings include FV50 configurations for up to 3-hour metal-door assemblies, subject to permitted leaf sizes, matching components and approved installation.
• 36-inch exit bar with 84-inch rods: Designed for 3-foot-wide by 7-foot-high doors. Confirm handing, door thickness, stile width, vertical rod lengths, strike positions and factory mounting pattern.
• Less dogging (LD): This configuration does not intentionally hold the latch retracted. Fire-exit devices must maintain positive latching; do not add ordinary dogging to the listed fire-rated assembly.
• Surface vertical rod system: Interior touchbar simultaneously releases the approved top and bottom latches. Compatible with manufacturer-approved pairs of doors without a fixed center mullion and other permitted fire-exit applications.
• Standard 96 surface top strike: Factory-specified 96 surface strike; Detex's standard V50 family bottom strike is 103546. Confirm the exact supplied components against the model-specific packing list.
• Heavy-duty construction: Ribbed aluminum rail extrusion, stainless-steel 3/4-inch deadlocking top latchbolt and the Detex manufacturer mounting plate and strike locator system.
• 628 satin aluminum or 711 satin black anodized: The standard no-alarm model, the 09BN-trim model and one EB model use 628 / US28 on the exit-device rail; the second EB model uses 711 black anodized. For FV5009BN LD, the accompanying BN lever/escutcheon is 689 Aluminum Painted, rather than 628 anodized. Match the selected finish to the door hardware schedule.
• EB alarm when selected: The two models with EB include Detex's 9V battery-operated audible exit alarm, nominal 100 dB sounder, arming indicators and signage as specified by EB-series literature. Both the standard FV50 LD and FV5009BN LD are non-alarmed versions.
• EB alarm cylinder requirement: A compatible 1-1/8-inch operating mortise cylinder with standard Yale-style cam is needed for manual arming/disarming on EB configurations and is sold separately. The standard non-EB device and FV5009BN LD model need no EB alarm cylinder. However, FV5009BN LD requires a separately purchased 1-1/8-inch compatible operating mortise cylinder and keys for the supplied 09BN storeroom trim. The exit-only and EB models do not include outside lever trim.
• Integrated 09BN storeroom outside trim — FV5009BN only: Factory-specified Detex 09BN narrow-escutcheon S-lever with Function 09 storeroom/night-latch operation. Outside entry requires key actuation; the lever locks after the key is removed. Mortise cylinder and keys are separate. Detex lists the 09BN trim in 689 aluminum-painted finish for the 628 device. Verify door handing and manufacturer-required trim fasteners and hole pattern.
• Commercial applications: Fire-rated commercial exits, schools, hospitals, warehouses, municipal buildings and institutional doors requiring approved SVR egress hardware.

Detailed Technical Specifications

Compare Standard, Storeroom-Trim and Alarmed FV50

Standard FV50 LD 628 — Without Alarm: Choose this exit device when a fire-rated, less-dogging, surface-vertical-rod egress assembly is specified but no built-in audible exit alarm is desired. This SKU has no EB battery, piezo alarm, exit-alarm indicators, or alarm arming cylinder requirement.

FV5009BN LD 628 — No Alarm, with Storeroom Trim: Select this factory package when an approved fire-rated FV50 surface-vertical-rod exit device must also provide key-controlled exterior reentry via 09BN narrow S-lever trim. Its Function 09 lever does not stay unlocked when the key is removed. The complete 09BN trim is included, but the operating mortise cylinder and keys must be specified and purchased separately. Its 628 satin-aluminum device rail is paired with 689 aluminum-painted lever trim.

FV50 EB LD 628 or 711 — With Battery Alarm: Choose an EB model when personnel should be alerted audibly when the exit is used. The EB series adds battery-powered alarm controls; verify alarm arming procedures and order the compatible operating mortise cylinder separately. EB is an audible alarm option, not delayed egress and not a device that restricts free egress.

What's Included

One genuine Detex FV50 fire-rated surface vertical rod exit-device assembly in the selected manufacturer configuration, supplied with the standard factory mounting, rod, latch and strike components applicable to that exact SKU. The EB models include manufacturer-specified battery alarm components, arming indicators and signage. The standard non-EB FV50 LD is supplied without a battery-operated exit alarm or outside trim. The FV5009BN LD is supplied without an exit alarm but with the 09BN Function 09 storeroom outside S-lever trim, matching its 628 rail with 689 aluminum-painted trim. The 09BN operating mortise cylinder and keys are not included. Verify the exact factory packing list for batteries (EB only), strikes, fasteners, rods, trim components and accessories.

Sold Separately

Exterior pull or lever trim for the three device-only configurations; operating mortise cylinder and keys for the supplied 09BN outside trim on FV5009BN LD; the EB alarm-control mortise cylinder and keys for EB models; any additional approved outside access hardware, special mounting or retrofit accessories, door, frame and installation labor. A separate delayed-egress power supply is not required for the non-alarmed model or Detex's 9V EB alarm as specified here.

Shipping Information

The Shopify carrier-weight setting is 25 lb per device-only variant (estimate) or 30 lb for the FV5009BN LD variant including outside trim (estimate). Neither is a manufacturer-verified packaged weight; check the supplier's actual shipping carton before calculating rates. This is a large commercial exit-hardware assembly; confirm carton dimensions and carrier handling rules before calculating actual freight or parcel charges.

Ordering, Installation and Life-Safety Notes

Confirm the exact FV50 model, desired alarm and outside 09BN trim configuration, 628 or 711 device finish, 689 painted finish on BN trim, door size, fire-door rating, handing, number of door leaves, surface-rod strike locations, door and stile preparation, approved mounting hardware, and any required 09BN operating cylinder/cam and keyway. Fire-exit hardware must maintain positive latching, including at the top and bottom. Do not add dogging or other modifications that compromise the approved fire-door assembly. Install and test in accordance with the latest Detex factory instructions, applicable building and fire codes, accessibility rules and the authority having jurisdiction.
